A. The paste must be stirred thoroughly. We recommend a wooden or plastic stick only.
B. When stirring the paste, wear a face-shield, gloves, and place the container of paste on top of a plastic sheet in case of spill.
C. The work-piece to be pickled must be cleaned/degreased before pickling. Pickling paste/spray are not degreasers. If the Stainless or Nickel is not cleaned, and the Pickling Paste/Spray are used, there is a good chance that you will not have the pickling effect wanted.
D. When the work-piece is at ambient temperature, use our acid resistant brush, which we supply with all Pickling/paste kits, to apply the pickling paste on area you wish to pickle.
E. The time that the pickling paste is to be left on the surface of the work piece depends on how heavy the oxide is, the grade of stainless stell/nickel you are pickling and the temperature you are pickling at.
Tig Weld-Light Oxide 30-45 min.
FCW/MIG-Heavy Oxide 60 min.
We recommend that on the Moly-Bearing Grades such as 316L/317L, pickling paste should be left on for the maximum amount of time.
WE STRONGLY RECOMMEND THAT YOU CONDUCT YOUR OWN QUALIFICATION PROCEDURE.
F. After the Pickling Paste has been on the work-piece for the determined amount of time, apply Antox neutralizing paste on top of the pickling paste. You will immediately see it bubble. As soon as it stops, you can wash the area with water/pressure water system.
NOTE: The neutralizing paste will not enable you to dispose of the residue in to the local sewage system. The neutralizing paste will turn the pickling paste on the work-piece from acidic to alkaline, and it would then be safer for the operator to remove it.
G. Use at a minimum, cold drinkable quality water to wash off the pickling residue. The optimum is to use
Collect the residue from the pickling operation, and then call your local contractor to arrange disposal in accordance with all local/federal regulations.
H. Re-seal pickling product container, and store in an ambient teperature room. If the storage temperature is too cold, it could increase the time for the Pickling product to work, or if it is too humid, it could give off nitric fumes, when apply the paste. In any case, it would be a good rule of thumb to let the pickling past sit for a while if it has been stored in too cold/humid of an area, before using it.
